We're only adding BCMs to the commit list in aggregate(), but there are
cases where pre_aggregate() is called without subsequently calling
aggregate(). In particular, in icc_sync_state() when a node with initial
BW has zero requests. Since BCMs aren't added to the commit list in
these cases, we don't actually send the zero BW request to HW. So the
resources remain on unnecessarily.
Add BCMs to the commit list in pre_aggregate() instead, which is always
called even when there are no requests.

The current probe/remove functions are implemented separately for each
target, but they are almost identical. Replace them with common
functions that can be used across all rpmh targets.

There is a link between the GEM NoC and C NoC nodes, which is currently
missing from the topology. Let's add it to allow consumers request paths
that use this link.

For creating an array with the members for each NoC, we should be using
a local indexes, as otherwise unnecessary large arrays would be created.
Using an incorrect indexes will also result error for the consumers when
they try to find a valid path between the endpoints. Let's fix this and
use the correct ids.

Add driver for the Qualcomm interconnect buses found in SM8350 based
platforms. The topology consists of several NoCs that are controlled by
a remote processor that collects the aggregated bandwidth for each
master-slave pairs.
